Although the Copa del Rey is a trophy which Zidane is yet to get his hands on during his short stint so far as Real Madrid boss, it is likely that he will see tonight as an opportunity to give game-time to those who are normally on the periphery.
There may be some surprise names in the starting line-up, with the French boss a big fan of rotation, such as Oscar, the 19-year-old midfielder who Zidane has seemingly taken a shining to.
Another highly-rated player who could feature in the youthful side is Jesus Vallejo. The 20-year-old centre-back could finally be set for his Madrid debut, after injury prevented him from starring for Los Blancos at an earlier stage.
Asensio is likely to be the main man and alongside him could be other fringe players like Diego Llorente or Borja Mayoral.
It certainly won't be Zidane's strongest eleven, but this Madrid 'B' team could still be enough to strike fear into third tier Fuenlabrada.
Possible Real Madrid starting XI: Casilla, Achraf, Nacho, Vallejo, Theo, Llorente, Oscar, Ceballos, Lucas Vazques, Asensio, Mayoral.
